Notes: - There are small differences in carbon dioxide emissions values between this table and Table11.2e due to differences in the methodologies for calculating the data. - Data are for emissions fromenergy consumption for electricity generation and useful thermal output. - The electric power sectorcomprises electricity-only and combined-heat-and-power (CHP) plants within the NAICS 22 category whoseprimary business is to sell electricity, or electricity and heat, to the public. - See Table 11.5c forcommercial and industrial CHP and electricity-only data. - See Note 2, "Classification of Power Plants IntoEnergy-Use Sectors," at end of Section 8. - See "Useful Thermal Output" in Glossary. - Totals may notequal sum of components due to independent rounding.
